Claim:
1. An open-end spinning rotor, comprising: a rotor cup; a rotor shaft; a coupling device configured between the rotor cup and the rotor shaft such that transmits a turning moment from the rotor shaft to the rotor cup and detachably connects the rotor shaft and the rotor cup; a magnetic axial coupling between the rotor cup and the rotor shaft; the rotor shaft comprising a projection with a turning moment transmitting area defined thereon; the rotor cup comprising a recess with a shape corresponding to the projection and a turning moment transmitting counter-area defined therein, wherein the projection fits into the recess for detachably coupling the rotor shaft and the rotor cup; a socket defined in a bottom or within a truss of the rotor cup for receipt of a permanent magnet component of the magnetic axial coupling; and wherein the projection comprises first section at an end towards the rotor cup, and a second section axially aligned with the first section, the turning moment transmitting area defined in the second section.
