Abstract
A ceramic turbine rotor fitted to a metal shaft has an integral stub shaft extending into the hollow end of the metal shaft, and is resiliently retained therein by a clamping and tightening member. In order to prevent relative rotation between the rotor and the shaft during torque transfer, the stub shaft within the metal shaft has a polygonal cross section, and the clamping member and the void on the hollow shaft have mating, but successively bigger cross sections.
