The invention relates to a sensor device (10) for a towing vehicle coupling (60) or as a component of a towing vehicle coupling (60), with which a trailer vehicle (A), in particular a semi-trailer, can be coupled to a towing vehicle (Z), in particular a truck, wherein the towing vehicle coupling (60) has a coupling element (61) for detachably coupling a coupling counter element (81), which are/can be secured to the towing vehicle (Z) and the trailer vehicle (A), and in the coupled state forming a joint, they can rotate relative to one another about at least one joint rotational axis (GZ), wherein the sensor device (10) has a follower (20), which is mounted on a bearing body (30) such that it can rotate relative to the coupling element (61) about a follower rotational axis (M), which can rotate about the follower rotational axis (M) by rotationally following the coupling counter element (81) in a rotation about the at least one joint rotational axis (GZ), and which is for detecting a rotation of the coupling counter element (81) relative to the coupling element (61) about the at least one joint rotational axis (GZ), and wherein the sensor device (10) has at least one sensor (11) for detecting a respective rotational position of the follower (20) relative to the bearing body (30) in relation to the follower rotational axis (M). According to the invention, the follower (20) is mounted such that it moves relative to the coupling element (61) for providing or maintaining a follower coupling to the coupling counter element (81) with at least one degree of freedom of movement that is different to the rotatability about the follower rotational axis (M).
