Watco’s Flex924 provides a solution for the misalignment between the bathtub overflow and the bathtub drain connection.  It has flexible PVC tubing that bends to connect the overflow to the sanitary tee of the bathtub.  It comes standard with a test membrane at the overflow and test plug for drains testable up to five floors.  The snap-on Innovator overflow plate assembles by hand, requires no screws and is easy to install. Because the overflow sticks through the tub and is locked into place with a retainer nut, it eliminates leaks due to loose or faulty overflow attachments.
