Zusammenfassung:Actuation assemblies include a valve assembly comprising a valve sleeve configured to rotate to selectively enable fluid flow through at least one aperture in the valve sleeve and into at least one port of an outer sleeve and a ball retention feature configured to selectively retain a ball dropped through a fluid passageway of the valve assembly in order to rotate the valve sleeve. Downhole tools include actuation assemblies. Methods for actuating a downhole tool include receiving a ball in an actuation assembly, rotating a valve sleeve of the actuation assembly to enable fluid to flow through a portion of the actuation assembly, and actuating a portion of the downhole tool with the fluid.
