Coupling and control assembly

A coupling and control assembly rotatable about a rotational axis,

• and comprising:
• a coupling assembly, including
• a first coupling member rotatable about the rotational axis and including a first coupling face having locking formations,
• a second coupling member rotatable about the rotational axis and including a second coupling face in opposition with the first coupling face of the first coupling member and having pockets, and a third face spaced from the second coupling face and having passages in communication with the pockets, and
• a plurality of locking members in the pockets to transmit torque between the first and second coupling members;
• and
• a control assembly, including
• a switchable linear actuator device having
• a stator including at least one electromagnetic source,
• a translator translatable along and rotatable about the rotational axis, and coupled to the second coupling member to be rotatable therewith, and including
• a permanent magnetic source that cooperates with the at least one electromagnetic source of the stator to translate the translator, and
• a housing in which the stator is carried,
• wherein the second coupling member is supported for rotation relative to the housing by a bearing between the housing and the second coupling member.
