Beschreibung
Zusammenfassung:	A device for detecting a twist angle and/or a torque of a shaft occurring on the shaft and methods for operating the device uses at least one first encoder and at least one second encoder at a predefined spacing therefrom. Each encoder influences at least one coil parameter, is associated with at least a part of the circumference of the shaft, and has at least one track having at least one period per revolution of the shaft. At least first and second inductive sensors scan the first and second encoders, respectively. Each inductive sensor provides a respective sensor signal reflecting at least one measure for the rotational angle of the shaft within the period, and a difference ascertainment unit ascertains and provides the twist angle of the shaft as an angle difference of the two rotational angles detected by the inductive sensors.
