A coupling device (11) and method of assembly, the device being of the type including a plenum member (17) disposed at one axial end of the coupling housing (13,15), the method comprising configuring the plenum member (17) such that each of the required features (55,57,61,66) is disposed circumferentially between an adjacent pair of fastener holes (18H). Next, the input ring gear (R) is installed about the housing (13,15) of the coupling device (11), from an axial end opposite said plenum member (17), into assembly position adjacent said flange portion (18). Each of a plurality (N) of fasteners (89) is inserted through one of the fastener holes (18H) and into initial threaded engagement with the input ring gear (R).
