I think that every adapter includes a driver. So a MySQL adapter for Rails includes driver information or utilizes a pre-existing driver for Ruby. The adapter then uses the raw data brought back from the database through an SQL statement that's been generated and makes an ActiveRecord object specific to the query and populates that object with the raw data.
