Assembly for connecting an actuator to a rotary valve

An assembly for use in removably connecting an actuator to a rotary valve wherein drive parts of each are adapted to be engaged with one another to impart rotation to the closure member of the valve, and the actuator has a mounting face with a circle of threaded holes and the valve has a mounting flange with a circle of bolt holes of different diameter than the threaded holes, comprising

• a plurality of studs each having one end for threaded connection to one of the threaded holes in the mounting face of the actuator,
• a segment mounted on the other end of each stud, wherein the segment being removably mounted to the mounting face of the actuator
• a spacer plate disposable between the mounting face and the mounting flange and having
• a central hole through which the drive parts may be connected, and
• circumferentially spaced slots each to closely receive and thus align a segment therein when back of the stud are threadedly connected with the holes in the actuator to draw the one side of the segment toward engagement with the mounting face of the actuator,
• each segment having a threaded hole which is adapted, when the segment is so aligned within said slots, for alignment with a bolt hole in the flange, and
• means including a plurality of bolts each for extending through a bolt hole in the flange for securing one end thereof with, a threaded hole in the segment so as to force and hold the flange tightly against the other side of the plate and thus the one side of the plate being forced tightly against the mounting face of the actuator as the plurality of bolts are threaded.
