A component assembly comprises a first housing and a second housing jointed by a coupling assembly. The coupling assembly comprises a coupling body and a floating torque ring axially slidably interfaced to the coupling body. The coupling body comprises a first threaded portion engaged with a first threaded coupling section of the first housing, and a second threaded portion engaged with a second threaded coupling section of the second housing. The floating torque ring is radially fixed to the coupling body, and is axially movable relative to the coupling body. Rotation of the floating torque ring causes relative rotation of the coupling body, thereby threadably joining the first housing and the second housing about the coupling body independent of axial positions of the housings due to the axially movable floating torque ring. A method of joining the housings is provided.
