Abstract

A drive device, which has a drive shaft mounted in such a way as to rotate about an axis, two driving cranks which are connected to the drive shaft in an angularly rigid manner in relation to the axis in the peripheral direction, and an output element which is connected to the drive shaft and transmits torque between the drive shaft and a load element. To enable the measurement of the torque transmitted by the shaft as easily and economically as possible, the drive device has at least one magnetostrictive sensor which is connected to the drive shaft in a fixed manner and axially arranged between a driving crank and the output element.
