摘要： Methods and apparatus to couple valve shafts and closure members are described. An example coupling apparatus includes an expansion pin to be disposed in a bore defined by a first aperture of a valve shaft and a second aperture of a closure member. The first and second apertures are coaxially aligned when the valve shaft is coupled to the closure member. A first tapered pin is disposed in a first opening of the expansion pin adjacent a first end of the expansion pin and a second tapered pin is disposed in a second opening of the expansion pin adjacent a second end of the expansion pin. The first tapered pin causes the expansion pin to expand at a first location when the first tapered pin is disposed in the first opening and the second tapered pin causes the expansion pin to expand at a second location different than the first location when the second tapered is disposed in the second opening.
