[TCML] Critical Coupling?

["Dex Dexter" <dexterlabs@xxxxxxxxxxx>]

In radio engineering critical coupling of 2
tuned coupled LC circuits is defined as:

k=1/SQRT(Q1*Q2)

Q1,Q2 are quality factors of first and second
circuit.

I notice that term "critical coupling" is 
often refered to in the context of tesla coils
and coiling as well.

Does it have the same meaning and definition
like in radio engineering?

If not,please explain what it is and give definition
of it.
