6. A rotary power transmission device, comprising:
a device housing having an interior in which multiple components are received for rotation;
a clutch ring received within the device housing and selectively engageable with one of said multiple components;
an actuator having a coil housing, a wire coil within the coil housing, and a plunger driven for movement along an axis and relative to the clutch ring to move the clutch ring relative to the device housing; and
a retainer having a first portion that extends axially and includes a radially inner surface that is received over a portion of the device housing and the radially inner surface that engages the device housing and the retainer has a second portion that extends from the first portion radially toward the axis, wherein the second portion radially overlaps the coil housing, does not radially overlap the wire coil, and limits axial movement of the coil housing relative to the device housing.
