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.

Manual valve operators having a locking device are described. An example manual operator includes a lever rotatably coupled to a locking plate and has a handle that pivots between a first position to prevent rotation of the lever relative to the locking plate and a second position to enable rotation of the lever relative to the locking plate. A lockout member is removably coupled to the handle. The handle has an aperture to receive at least a portion of the lockout member. The lockout member engages a portion of the lever to prevent the handle from pivoting between the first and second positions to prevent rotation of the lever relative to the locking plate when the lockout member is coupled to the handle.
