Having thus described the preferred embodiments, the invention is now claimed to be: 1. A central shaft assembly for transmitting rotational power, comprising: a drive assembly including a rotor and a first rotating shaft having an axis of rotation; a first rotating magnet rigidly mounted coaxially about said rotating shaft; a first stationary housing sealing said first rotating magnet from environmental contamination, said rotating shaft rotatably supported within said first stationary housing; a second rotating magnet rotatably supported on said housing about said axis of rotation in axial alignment with said first rotating magnet; a first rotating housing including a coaxial sleeve portion receiving the second rotating magnet and coupled thereto and an axially extending member defining an axial bore, said first rotating housing rotatably supported on said first stationary housing; a second rotating housing including a second coaxial sleeve portion and a second axially extending member, said first and second axially extending portions axially overlapping and interlocking; a third rotating magnet received within said second coaxial sleeve portion; a fourth rotating magnet; a second stationary housing receiving said fourth rotating magnet and sealing said fourth rotating magnet from environmental contamination; said third rotating magnet and said second rotating housing rotatably supported on said second stationary housing about said axis of rotation, said third rotating magnet in axial alignment with said fourth rotating magnet; said first stationary housing including an third axially extending member and said second stationary housing including a fourth axially extending member, said third and fourth axially extending members overlapping and interlocking within said axial bore; and a second rotating shaft coupled to and rotating with said fourth rotating magnet. 2. The central shaft assembly of claim 1, further comprising a third rotating shaft coupled to said first rotating shaft. 3. A cooling apparatus of a type for circulating a cooling fluid through a cooling garment for removing heat from the body of a user donning the cooling garment, comprising: a refrigeration unit including a compressor, a condenser, and an evaporator; a motor driving a first rotating shaft for delivering rotational power to said compressor; a pump for circulating the cooling fluid; a heat exchanger in fluid communication with said pump for transferring heat absorbed by the cooling fluid to a refrigerant in said refrigeration unit; a second rotating shaft for delivering rotational power to said pump; and a sealed magnetic drive coupling between the first rotating shaft and the second rotating shaft. 4. The cooling module of claim 3, further comprising an elongate housing, said module adapted to mount to a breathing apparatus in place of a breathing gas tank. 5. The cooling module of claim 3, further comprising a hydration system delivering a potable fluid to a user. 6. The cooling module of claim 5, wherein said hydration system includes a pump for delivering a potable fluid to a user under pressure. 7. A garment pass-through connection system for coupling an external cooling unit through a plurality of garment layers to a cooling garment fluid channel for circulating a cooling fluid, comprising: a first fluid connector for fluid connection to the external cooling unit; said first fluid connector disposed on an exterior surface of an outer protective garment; a first retaining plate disposed on an interior surface of the outer protective garment and secured to the first fluid connector; a second fluid connector for fluid connection to the cooling garment fluid channel; said second fluid connector disposed on an interior surface of the cooling garment; a second retaining plate disposed on an exterior facing surface of the cooling garment and secured to the second fluid connector; the first and second fluid connectors adapted to be releasably connected to define a flow passageway between the external cooling unit and the cooling garment fluid channel.
