'Return a new :class:`.Connection` object.
The :class:`.Connection` object is a facade that uses a DBAPI
connection internally in order to communicate with the database.  This
connection is procured from the connection-holding :class:`.Pool`
referenced by this :class:`.Engine`. When the
:meth:`~.Connection.close` method of the :class:`.Connection` object
is called, the underlying DBAPI connection is then returned to the
connection pool, where it may be used again in a subsequent call to
:meth:`~.Engine.connect`.'
