An actuator plug is an artificial intelligence-adjacent technology used by the Covenant and its various remnants, including the Banished. Due to the Covenant's religious doctrines, the empire restricted the use of volitional intelligences, and thus was unable to wield their power to the same extent as the United Nations Space Command.

Equipment known to make use of actuator plugs include the, , and Banished automated turret. The is fitted with twin medium plasma cannons, automatically operated by "dummy modules" - which are likely an alternate method of referring to actuator plugs.

Humanity have developed their own actuator plug technology. The RANGER-class Mjolnir armour set makes use of the 7P-LCF actuator plugs in its chest plate for managing the suit's energy shielding.
