Claim 2:
3. An overfill prevention valve, comprising:
a conduit having a first end and a second end, a conduit wall spanning said first end of said conduit and said second end of said conduit, said conduit wall defining a conduit wall interior surface and a conduit wall exterior surface, said conduit wall interior surface defining a fluid path through said conduit from said first end of said conduit to said second end of said conduit;
a flapper valve hinged to the conduit, the flapper valve hingeable from an open position to a blocking position, the blocking position obstructing a flow though the conduit;
a float moveable via buoyancy between a filling position corresponding to the open position of the valve body and an overfill-prevention position corresponding to the blocking position of the valve body;
an outer magnetic coupler associated with the float so that a float movement via buoyancy between the filling position and the overfill-prevention position causes the outer magnetic coupler to rotate; and
an inner magnetic coupler magnetically coupled to the outer magnetic coupler;
wherein rotation of the outer magnetic coupler causes corresponding rotation of the inner magnetic coupler which causes movement of the flapper valve from the open position toward the blocking position.
