A device for measuring torque in a drive assembly includes a torque-loaded torsion element (9), such as a shaft, and a reference element (21) surrounding the torsion element (9). The reference element is correspondingly tubular in shape. A first tube end (22) of the reference element (21) is firmly connected to a first shaft end (10) of the torsion element (9). A second tube end (24) of the reference element (21) is supported on the second shaft end (11) of the torsion element (9). The two tube ends (22, 24) are each associated with a transmitter element (16, 34). The relative position of the transmitter elements (16, 34) in the direction of rotation around the rotational axis (8) is recorded by a sensor element (35). The sensor (35) is associated with a housing (1). The sensor (35) generates a signal each time the two transmitter elements (16, 34) pass and transmits signals to an evaluation unit (36). The evaluation unit (36) determines the torque applied from the offset of the signals.
