Abstract

The invention relates to a sensor arrangement (1) for indirectly sensing the torque of a rotatably mounted shaft (5), said sensor arrangement (1) having a sensor (10) comprising at least one sensor element (30) that is arranged in the area of a bearing (7) for the shaft (5) and senses a bearing force (FL1) which acts in a defined direction and from which the torque of the shaft (5) can be calculated. According to the invention, the sensor (10) includes a sensor body (20) acting as a deformable body, an inner ring (26) that surrounds the bearing (7), and an outer ring (22) which is connected to a supporting structure (3) and is joined to the inner ring (26) by at least two connecting sections (24), the at least one sensor element (30) being coupled to one of the connecting sections (24).
