The invention relates to a sensor system for detecting the angle of rotation and/or the torque of rotating mechanical components (1). The rotating component comprises a torsion shaft which is configured as an external shaft (3). A torque is applied to one region (2) at the end of said shaft and can be removed in the region (5) at the opposite front end of the shaft. An internal shaft (7) is positioned concentrically in relation to the external shaft (3) and one end of the internal shaft is connected to the external shaft (3) in the region (2) of the entry point of the torque. The front end of the external shaft (3) and the internal shaft (7) are preferably provided with magnets (8, 10) with magnetic fields which lie in a radial direction in relation to the shaft axis, to which a respective fixed sensor is allocated. The relative torsion of the magnetic fields in relation to each other can be measured under the effects of the torque, the angle of torsion being proportional to the torque angle.
