According to the Gang of Four, the intent of the Adapter pattern is to

Convert the interface of a class into another interface that the clients expect. Adapter lets classes work together that could not otherwise because of incompatible interfaces.^[1]

Basically, this is saying that we need a way to create a new interface for an object that does the right stuff but has the wrong interface.
