Im elastischen Bereich ist das wirkende Drehmoment M dem Torsionswinkel proportional. Dieser Zusammenhang läßt sich wie folgt darstellen:
M = Dw x .
Der Proportionalitätsfaktor Dw ist die Winkelrichtgröße. Diese physikalische Größe ist vom Material und den Abmessungen des Drahtes abhängig. Sie kann aus dem Anstieg der Geraden im Diagramm bzw. dem Quotienten aus dem Drehmoment M und dem Torsionswinkel ermittelt werden.
For the physicists among us - what is the proper English term for "Winkelrichtgroesse"? Is that the torsion coefficient? TIA, Susanna

torsion coefficient
As a physicist, I'd say that "torsion coefficient" is just fine. It is used in English almost as widely as "torsional spring constant" (to describe the same quantity), and has the advantage of being closer to the German. Compare the refs below:

With respect, I think you're being a little over-worried here. Even in physics, there are often multiple names for a particular quantity. "Torsional spring constant" and "torsion coefficient" are both perfectly valid names for this quantity, even in the case of a straight wire; it's just that I'd go for the latter for your translation.

Note from asker:
| Ah, finally a physicist. I don't really think that spring constant is a good fit here; after all, this is about the elastic properties of a straight wire. Not that I mean to make a pest of myself, but this is one of those unfortunate terms where there is a gazillion of plausible guesses, but only one correct translation.. |

German term (edited):
Winkelrichtgroesse
Definition - not for points
Die Winkelrichtgröße beschreibt bei Drehschwingungen die vom Auslenkungswinkel abhängende Rückstellkraft.
Damit ist die Winkelrichtgröße die Federkonstante der Drehschwingung, die Rückstellkraft wird jedoch über eine Spiralfeder erzeugt. Bei Drehschwingungen ist das an der Drehachse entgegengesetzt zur auslenkenden Kraft angreifende Drehmoment proportional zum Winkel der Auslenkung.
Formelzeichen der Winkelrichtgröße: D* (D-Stern)

angular benchmark?
How many degrees will the door open at most, with D* as the "angular benchmark"? Use the numbers M = 10 kg, b = .6 m, m = 10 g, v = 500 m/s, D* = 1.2 Nm. - I don't even know if "angular benchmark" is the right translation for D* (it's Winkelrichtgroesse in German if that helps anyone). We were also given the formula Moment of Force = -D*phi. Am I going to want to plug the info I'm given into the formula I created in b?
http://www.physicsforums.com/archive/index.php/t-20663.html
A 20-propagation on the angular benchmark corresponds with a carriage stroke equal to b/18.
The high shutter speed camera provides sufficient accuracy for the determination of the slippage point. However, the judgment of whether slipping occurs is rather subjective. We assume here that the observer of the experiment is able to provide this judgment within an accuracy of 50% on the angular benchmark, placed on the mandrel. This uncertainty corresponds with 10 on the benchmark, thus 1/36 of the roving width.

torsional spring constant
With thanks to Kim for providing the definition.
Other names involving 'coefficient' (such as spring coefficient), which is closer to the German, are also possible, but IMO 'spring constant' is standard engineering usage.
refs:
The period of a Torsional Pendulum is measured and compared to the theoretical value. The torsional pendulum consists of a torsion wire attached to a Rotary Motion Sensor with an object (a disk, a ring or a rod with point masses) mounted on top of it. The period of oscillation is measured from a plot of the angular displacement versus time. To calculate theoretical period, the rotational inertia is determined by measuring the dimensions of the object. The torsional spring constant is determined from the slope of a plot of force versus angular displacement.

In Lateral Force Microscopy, the torsional spring constant, which relates the applied torque to the angle of twist of the cantilever is important (see Fig. 2 below for a schematic).
