1. A rotary power transmission device, comprising:
a housing having an interior in which multiple components are received for rotation, and wherein the housing has an annular surface;
a clutch received within the housing and having a clutch ring selectively engageable with one of said multiple components;
an actuator having a coil and a plunger driven for movement along an axis and relative to the clutch, the plunger being received over and movable along the annular surface, and the plunger having a limit surface; and
a retaining body having a blocking surface radially overlapped with the limit surface and arranged to be contacted by the limit surface to prevent removal of the plunger from the annular surface, and wherein the retaining body is carried by and extends radially outward of the annular surface, wherein the housing includes a groove located in a portion of the annular surface over which the plunger is received and movable along and the groove extends radially inwardly into the housing from said portion of the annular surface, and the retaining body is an at least partially annular body that is partially received within the groove and extends out of the groove radially beyond the annular surface.
