Beschreibung
Zusammenfassung:	A connecting module interposed between a drive shaft of an aircraft engine fan and a rolling-element bearing, wherein the module includes an inner structure attached to the shaft and including a bonnet, and an outer structure attached to the bearing, which is radially supported on a mechanism installed on the inner structure and delimiting a raceway which is complementary to the bonnet so as to form a ball-joint connection kept in a blocked state by a blocking device installed on the inner structure and protruding radially from the bonnet, wherein a mechanism forming a mechanical fuse provides a junction between the device and the bonnet, such that the ball-joint connection is released following fracture of this mechanism forming a mechanical fuse. The radial support mechanism is added to the device.
