The present invention relates to a sensor assembly (01) for sensing a steering torque and an absolute angular position of a steering element (02) extending along an axis (03). The sensor assembly (01) comprises a circuit board (04), a first sensor element (06) and a second sensor element (07). The circuit board (04) has a base surface (08) arranged perpendicularly to the axis (03) and at least one wing surface (09) running at an angle to the base surface. The first sensor element (06) is used to determine the steering torque and consists of at least one first primary sensor (11) in the form of a magnetically coded portion on the steering element (02) and one secondary sensor (12) facing the first primary sensor (11) for converting the change in a magnetic field generated by the primary sensor into an electrical signal. The secondary sensor (12), which is arranged on the wing surface (09), faces the primary sensor (11). The second sensor element (07) is used to determine the absolute angular position. The second sensor element (07) comprises a main gear (13), which is arranged on the steering element (02) and meshes with at least two gears (14). One of the two gears (14) has one more tooth than the other gear (14). Each gear (14) has a target (17), and the targets face respective angle sensors (16) arranged on the base surface (08) of the circuit board (04). The invention further relates to a sensor device having the sensor assembly (01).
