1. An exterior actuator assembly for a manually driven electronic deadbolt assembly and configured to operate a deadbolt mechanism from an exterior space via a torque blade, the exterior actuator assembly having a locked condition and an unlocked condition, the exterior actuator assembly comprising:

  • a cylinder body;

    an exterior turnpiece rotatably mounted to the cylinder body;

    a torque blade driver coupled to the torque blade, the torque blade driver having a perimetrical lock recess, the torque blade driver being rotatable about a first rotational axis;

    a clutch assembly drivably interposed between the exterior turnpiece and the torque blade driver;

    a motor having a motor shaft arranged to rotate about a second rotational axis that is non-coaxial with the first rotational axis;

    a locking shifter mounted to the cylinder body and configured for axial translation along the second rotational axis, the locking shifter having a blocking tab portion configured for selective engagement with the perimetrical lock recess of the torque blade driver;

    a rotational-to-linear motion converter drivably interposed between the motor shaft and the locking shifter and configured such that a rotation of the motor shaft in a first rotational direction about the second rotational axis results in an axial displacement of the locking shifter in a first longitudinal direction to a locked position corresponding to the locked condition wherein the blocking tab portion of the locking shifter is engaged with the perimetrical lock recess of the torque blade driver to prohibit rotation of the torque blade via the exterior turnpiece, and a rotation of the motor shaft in a second rotational direction about the second rotational axis results in an axial displacement of the locking shifter in a second longitudinal direction to an unlocked position corresponding to the unlocked condition wherein the blocking tab portion of the locking shifter is disengaged from the perimetrical lock recess of the torque blade driver to permit rotation of the torque blade via the exterior turnpiece.
