Component assembly for high-precision joining of components

A component assembly, comprising:

• a first housing comprising a first raised portion that extends inward toward a center of the first housing, the first raised portion comprising a threaded coupling section and an inner mating section;
• a second housing comprising a second raised portion that extends inward toward a center of the second housing, the second raised portion comprising a threaded coupling section and an inner mating section;
• and
• a coupling assembly joining the first housing to the second housing, the coupling assembly comprising:
• a coupling body comprising a first threaded portion engaged with the threaded coupling section of the first housing, and a second threaded portion engaged with the threaded coupling section of the second housing;
• and
• a floating torque ring axially slidable relative to and engageable with the coupling body,
• wherein rotation of the floating torque ring causes rotation of the coupling body, and drawing of the first and second housings together to press against the floating torque ring, thereby joining the first housing and the second housing about the coupling body independent of an axial position of the first housing relative to an axial position of the second housing.
