Abstract

In a known measuring value transmitter for registering a torque, hysteresis-like deviations occur in the measurement result, and this is to be avoided. The measured value transmitter (10) has a torsion shaft (14) on which there are arranged two axially spaced shaft collars (15, 16). Connected to the shaft collars (15, 16) in each case is a measuring sleeve (24; 25), which are arranged coaxial to the torsion shaft (14), engaging in each other and displaceable with respect to each other. The measuring sleeves (24, 25) are provided in their end region, provided for connecting to the torsion shaft (14), with a plurality of longitudinal slits (28), as a result of which the torsional stiffness of the measuring sleeves in this region can be reduced and plastic deformations at the connecting point can be avoided. <IMAGE>
