1. A device (1) for determining the torque and/or the rotary angle between a first shaft (10) and a second shaft (20), which are coupled via a gear mechanism (30) to rotate relative to one another about an axis of rotation (A),
wherein the first shaft (10) has a first end region (10a), a second end region (10b), and a first direction vector (R1) pointing parallel to the axis of rotation (A) from the first end region (10a) to the second end region (10b),
and wherein the second shaft (20) has a first end region (20a), a second end region (20b), and a second direction vector (R2) pointing parallel to the axis of rotation (A) from the first end region (20a) to the second end region (20b),
characterized in that:
the first shaft (10) is designed as a hollow shaft and the second shaft (20) is arranged coaxially in the first shaft (10) in such a way that the first direction vector (R1) and the second direction vector (R2) have the same orientation;
the first end region (10a) of the first shaft (10) has a first measurement standard (11) and the first end region (20a) of the second shaft (20) has a second measurement standard (21), the first measurement standard (11) being scanned by a first sensor (41) and the second measurement standard (21) by a second sensor (42),
wherein the first and second sensors (41, 42) are arranged frontally in front of the first end regions (10a, 20a) of the two shafts (10, 20).
