A system and method is provided for easily and securely coupling objects together. In some examples, a coupling mechanism enables a user to install, remove, or replace conventional light bulbs (116) in conventional light bulb sockets (114), without the need to rotate the light bulb (116) several revolutions. A coupling mechanism uses a first adapter (112) threaded onto a conventional light bulb (116) and a second adapter (110) threaded onto a conventional light bulb socket (114). The first and second adapters (112, 110) use a combination of mechanical and magnetic coupling techniques to secure the light bulb (116) to the socket (114).
