Abstract

Torsion in a shaft with two portions or a torsion bar caused by a torque is initially converted into an angular movement of a disc-shaped movement converter fastened to the first portion. A carrier surrounding the shaft as a sleeve is fastened to the second portion and converts the angular movement into an axial translation movement of the carrier which can be detected by a contactless displacement sensor.
