A power transmission arrangement comprises a first power transmission member connectable to a first main shaft of an engine. The arrangement also includes a second power transmission member connectable to a second main shaft of the engine and to a third power transmission member. A coupling assembly is provided which has a selectable coupling condition to couple the first power transmission member to the second power transmission member to allow power to be transmitted from the third power transmission member to the first main shaft of the engine via the first power transmission member. The coupling assembly has a decoupling condition to decouple the first power transmission member from the second power transmission member to allow power to be transmitted from the main shaft of the engine to the third power transmission member via the second power transmission member.
A power transmission arrangement comprising a first power transmission member connectable to a first power assembly of a drive arrangement, a second power transmission member connectable to a second power assembly of a drive arrangement and to a third power transmission member, characterised by a coupling assembly having a selectable coupling condition to couple the first power transmission member to the second power transmission member to allow power to be transmitted from the third power transmission member to the first power assembly via the first power transmission member, and having a selectable decoupling condition to decouple the first power transmission member from the second power transmission member to allow power to be transmitted from the second power assembly to the third transmission member via the second transmission member.
A drive arrangement comprising first and second power assemblies and a power transmission arrangement according to any preceding claim, wherein the first power assembly is connected to the first power transmission member, and the second power assembly is connected to the second power transmission member.
A coupling assembly comprising a main body having a first part selectively coupled by fluid to a second part, the first part being mountable on a first power transmission member and the second part being mountable on a second power transmission member, the main body defining a space to receive at least one of the power transmission members, and the coupling assembly further comprising fluid supply means for supplying fluid to the main body via a region of the main body outside the aforesaid space.
