A rotary encoder is clamped coaxially with its pickup shaft ( 14 ) on a drive shaft ( 12 ) which is to be measured. Two collet chucks are provided for this purpose. The one collet chuck is constructed as a clamping sleeve, which penetrates the pickup shaft ( 14 ) axially and has clamping jaws ( 34 ) on its free end. The other collet chuck is constructed as a clamping ring, which engages the pickup shaft ( 14 ) with clamping jaws ( 38 ). The two collet chucks are clamped axially against each other and against the pickup shaft ( 14 ) by a force element ( 40 ).
