A torque tube assembly includes a hollow composite member and an end
fitting. The composite member has at least one end portion divided into a
forward section and an aft section. The forward section is disposed
adjacent a free end of the composite member. Each one of the forward and
aft sections has at least one lobe extending radially outwardly along a
lobe axis. The lobe axis of the forward section is preferably angularly
offset from the lobe axis of the aft section. The end fitting is formed
complementary to the composite member and is at least partially enclosed
by the forward and aft sections.
