is there a wii to ps2 adapter?

[jaguarsteps]

i tried searching hard to find a nintendo wii to ps2 controller adapter but i can't find one.

all i ended up finding are ps2 to wii adapaters.

does anyone know if i can just reverse the use of a "ps 2 to wii" adapter?

this is the "ps2 to wii" adapter that i'm talking about,

would i be able to plug a wii controller into this adapter to play on my ps2? or is it ps2 to wii only?
