Abstract
A device for measuring torque in a shaft, e.g. for controlling a power-assist steering arrangement for a vehicle, in which two rotatable parts of a shaft are coupled together by an elastic body while one of the shaft parts comprises a magnet and the other has a differential field plate sensor responsive to the position of the magnet relative to the sensor for generating an analog output representing the torque exerted between the parts of the shaft and hence the torque applied to the latter in rotating the shaft. The magnet lies opposite the center of the differential field plate sensor in an unloaded condition of the shaft.
