1. An apparatus, comprising: an adapter configured to attach to a flush mechanism configured to provide for a predefined flush capability in a toilet, the adapter comprising a circular attachment ring and a mounting flange located at an attachment point on a circumference of the circular attachment ring, the mounting flange substantially perpendicular to a diameter of the circular attachment ring that extends from the attachment point and passes through a center of the circular attachment ring; the mounting flange comprising a side opposite the adapter including first and second linear end sections that are substantially aligned, and have a thickness, and a central concave section configured to vertically align with a down tube, where the central concave section curves inward from the side opposite the adapter to a depth that is substantially the thickness of the first and second linear end sections; a gasket attached to the adapter, the gasket forming a seal between the flush mechanism and a flush orifice of a flush valve, where the flush valve is configured to seat a sealing member; and means for securing the gasket in position with respect to the flush orifice of the flush valve comprising a mounting ring configured to be secured around the down tube of the flush valve when fastened to the mounting flange, where the adapter is radially offset from the down tube of the flush valve by a shim positioned between the mounting flange and the down tube, and substantially tangent to a circumference of the down tube, to align the gasket with the flush orifice.
