1. A measuring device for determining a torque on a torque-transmitting shaft which is supported by a bearing apparatus, an output shaft or an input shaft of the bearing apparatus being formed by the torque-transmitting shaft, the measuring device comprising:
at least two piezoelements and a fixing device, wherein the fixing device supports the at least two piezoelements, and wherein the fixing device and the at least two piezoelements are, for determining the torque, configured to measure a shear force between the bearing apparatus and a supporting apparatus for supporting the bearing apparatus.
