An actuator mounting device for mounting an actuator having an actuator housing to a support structure associated with a fluid flow control unit. The actuator mounting device includes a mounting bracket and a pair of guide members. The mounting bracket includes a pair of spaced side walls, a rail extending from each side wall, and a stop. The pair of spaced side walls define a leading end and a trailing end. Further, each of the side walls has a base portion securable to the support structure. Finally, the stop is positioned at the trailing end of the spaced side walls. The pair of guide members are each configured to be mountable to an opposing side of the actuator housing and each include an engagement surface configured to slidably engage one of said rails. During assembly of the actuator to the support structure, the rails direct the guide members to a secured position at which the actuator housing is connected to the stop.
