Beschreibung
Zusammenfassung:	The invention relates to a module (3) comprising a device (45) for changing the pitch of the vanes (30) about the pitch axes (C) thereof, said device (45) comprising: a hydraulic actuator (46) capable of rotating about the longitudinal axis (X) and configured to rotate the vanes (30) about their pitch axes (C), a supply pump (54) for supplying fluid to the hydraulic actuator (46), said supply pump (54) comprising a drive shaft capable of rotating about the longitudinal axis (X) and a shell that is rotationally fixed relative to the longitudinal axis (X), and an electric machine (55) configured to operate the supply pump (54), the electric machine (55) comprising a rotary member for driving the drive shaft and a fixed member that is rotationally fixed relative to the longitudinal axis (X).
