Abstract
A system for attaching the end of a shaft of a gas turbine engine engaged inside a coupling supported by a bearing is disclosed. The system includes a nut with a first thread which is screwed into the shaft and a second thread which is screwed to the coupling. Advantageously, the screw pitches of the two threads of the nut are reversed relative to one another so as to form an adjusting nut.
