An actuation device for a steering lock is operable to selectively lock a rotary steering member against rotation. A lockbolt is movable along a first axis between a steering member-locking position and a steering member-unlocking position. A shuttle is movable between a non-blocking position in which the shuttle does not obstruct movement of the lockbolt from the steering member-locking position to the steering member-unlocking position and a blocking position in which the shuttle obstructs movement of the lockbolt from the steering member-locking position to the steering member-unlocking position. An actuator is coupled to the shuttle and operable to move the shuttle from at least one of the non-blocking position and the blocking position to the other of the non-blocking position and the blocking position. The actuator has an output defining a second axis that is substantially perpendicular to the first axis.
