Beschreibung
Zusammenfassung:	The invention concerns a method and device for a drive shaft (6), which drive shaft is arranged at its first end for operative connection with a drive mechanism (4) that applies a first torque to the drive shaft, and which drive shaft is arranged at its second end for operative connection with a mechanism (9) driven by the drive shaft. The invention is characterized in that the drive shaft (6) has, at at least one of its ends, a notch (15) arranged so as to receive a connector (12, 10) for the associated mechanism, and in that the wall (7) of the notch is made, in at least one area at said end, of fiber composite material comprising a first set of fibers that extends into the notch wall in a direction falling roughly within a range of +( 10° -80°) relative to the longitudinal direction of the drive shaft, where the positive range of angles indicates that the fibers are oriented in the first direction of torque. The first torque is thereby arranged so as to bring about transverse contraction of the shaft in said notch area so as to impose a clamping grip on the associated mechanism connector.
