An adjustable kinematic coupling for accurate and precision coupling of mechanical component parts, surfaces or assemblies and the like, where low-cost, accurate, and repeatable coupling are desired. One of the components further includes a radially extending abutment shoulder at an end of the first threaded portion away from the second threaded portion which abuts against the other component. The control circuitry includes a detecting circuit connected to the sensor for providing a detection signal related to an imbalance between the first and second capacitances, and a processor for receiving the detection signals and providing a display signal. The mounting member has a second end with a coupling having external threads complementing the internal threads of the first coupling to enable a plurality of the mounting members to be coupled together and forming a weatherproof connection between the adjacent mounting members. The data may be shared between components using existing timing interfaces, thereby saving the cost associated with the design, verification and manufacturing of new andor additional hardware. The infrared emitting diodes receive power from an external electrical source entering the system through the base.
