Claim 0:
1. Sensor device for a towing vehicle coupling or forming part of a towing vehicle coupling with which a trailer vehicle can be coupled to a towing vehicle wherein the towing vehicle coupling has a coupling element for releasably coupling a coupling mating element, which elements are configured to be secured to the towing vehicle and the trailer vehicle, and when coupled can rotate relative to each another about at least one joint rotational axis, forming a joint, wherein the sensor device has a follower which is mounted on a bearing body such that it can rotate relative to the coupling element about a follower rotational axis and can be rotatably carried about the follower rotational axis by the rotation of the coupling mating element about the at least one joint rotational axis in order to sense a rotation of the coupling mating element relative to the coupling element about the at least one joint rotational axis, and wherein the sensor device has at least one sensor for sensing a respective rotational position of the follower relative to the bearing body in relation to the follower rotational axis, wherein it has an actuator for moving at least the follower between a follower position closer to the coupling mating element and a release position further away from the coupling mating element, wherein the actuator can be controlled with the aid of a control device in order to move the follower.
