1. A rotary lock system, comprising:
a rotatable starter component; and
a driven gear configured to engage and to drive rotation of the rotatable starter component via an interface that comprises a circumferential gap to enable the driven gear to circumferentially rotate in a sequence of:
a first rotational motion through an angle to close the circumferential gap, wherein the driven gear does not apply a sufficient torque to rotate the rotatable starter component during the first rotational motion; and
a second rotational motion after closure of the circumferential gap and contact between opposing surfaces of the driven gear and the rotatable starter component, wherein the driven gear applies a full torque to rotate the rotatable starter component during the second rotational motion.
