Abstract
A worm shaft coupling for connecting a driven shaft of a transmission mechanism and a coaxially arranged worm shaft of an extruder has a coupling sleeve which connects two coupling pegs in a torque-proof manner and is, in turn axially secured using threaded sleeves. The internal thread of the threaded sleeve facing the worm shaft of the extruder and the associated external thread of the coupling sleeve have recesses allowing the threaded sleeve and the coupling sleeve to be connected in the manner of a bayonet fixing.
