Kopplings

Kopplings is a general term used to describe the concept of coupling or connection between two or more components, systems or signals. It is applied across disciplines to indicate how parts are linked, how energy or information is transferred, or how one subsystem influences another. In practice the exact meaning depends on the context, ranging from mechanical devices that transmit motion to electrical interfaces that join circuits.

In mechanical engineering, kopplings refer to devices that connect moving parts to transmit torque or motion, such as clutches, couplers, and other linkage mechanisms. These components are chosen to match loads, speeds, and alignment requirements, and they often aim to allow disengagement or damping of forces.

In electrical engineering and electronics, kopplings describe interfaces and arrangements that connect circuits or enable energy and signal transfer. This includes connectors, coupling networks, and methods for transferring signals between stages, with attention to impedance, isolation, and noise.

In control theory, physics, and systems engineering, koppling describes the interaction strength between subsystems. It is quantified by coupling coefficients, transfer functions, or other metrics that describe how one part of a system affects another.

Etymologically, kopplings is related to koppling, a term borrowed into Swedish from Germanic roots meaning a bond or link. The standard plural form in Swedish is kopplingar; kopplings appears in compound phrases or in certain linguistic contexts.
