A coupling mechanism between a control member (1′) that generates manual flight commands and a trim actuator (4) forming part of a mechanical transmission train for transmitting flight commands in an aircraft. The coupling mechanism comprises axial engagement means between a lever arm (3) mechanically connected to the control member (1′) and a pivot shaft (10) forming part of the trim actuator (4). The axial engagement means comprise co-operating interlocking members (13, 14) arranged on coupling members (18, 19) constrained to move in rotation respectively with the lever arm (3) and with the pivot shaft (10). Each of the coupling members (18, 19) includes axial passages (26) enabling the other coupling member (18, 19) to pass axially therethrough. An interruption of said axial engagement causes the coupling members (18, 19) to move axially one through the other under the effect of axial thrust (P) exerted by elastically deformable means (15) used for obtaining said axial engagement.
