An apparatus and method for installing a plurality of rotary actuator segments in a device includes a unitary hinge fitting. The unitary hinge fitting includes a first side couplable to a control surface, and a plurality of bays. Each bay is configured to receive at least one of the rotary actuator segments. The unitary hinge fitting reduces the number of components required to install rotary actuators by eliminating the shims, the shear clips, and some of the fasteners required to attach the shims and the shear clips to the hinge fittings. The resulting assembly is typically much simpler and lower in cost and weight than conventional rotary actuator installations.
