The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore () having an internal thread () at least on the end facing the rotor hub (); a threaded pin () constructed as a separate component is disposed in both central bores () in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces () and contact surfaces ().
