   • The act of joining or linking two things together: "coupling" can refer to the action of connecting two separate items, parts, or systems.
   • A device that connects two mechanical parts: In engineering, a "coupling" is a physical component used to join the ends of adjacent shafts or objects, allowing them to rotate together and transmit power.
   • The pairing of two entities, especially for a specific purpose: This can refer to the pairing of a male and female for reproduction, or more broadly, the linking of two ideas, systems, or concepts.
