An actuator includes a housing, a motor that is mounted to the housing and operatively coupled to an output shaft, a first PCB that is arranged in the housing near the motor and includes a motor circuit, a second PCB that is arranged in the housing and spaced at a gap from the first PCB, and an electrical adapter that is arranged in the gap and operatively electrically connects the first and second PCBs. The adapter includes first and second ends opposite one another, and electrical elements extend between the first and second ends to first and second terminals that are respectively provided at the first and second ends. The electrical elements are arranged in a rigid enclosure that is configured to maintain the first and second terminals in fixed relationship to one another during assembly of the actuator.
