The coupling elements of aircraft instruments are of manydifferent designs depending on the instruments own design and use. Pneumatic pressures from static and pitot systems are used for airspeed indicators and older models are plumbed. Altitude uses the static system only but is also plumbed. We could go through all the flight and engine instruments but I have the feeling you are looking for the most common answer, CANNON PLUGS. Cannon plugs are hermetically sealed pin and receptor connections that screw together only when properly aligned. The cannon plug has been around a very long time.

Different aircraft have different brands of avionics, but the C-17 and C-5 aircraft have Honeywell avionics.
Aircraft and ships use GPS locators for precise positioning.

There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
