To make predictions in physical space we must project the configuration wave function model onto physical space to compute the probability that an event will be observed at a detector. The combination of wave function evolution in configuration space and this projection operation is irreducibly nonlocal. The only way to model what is happening mathematically is for information to be transferred superluminally from one of the polarizers to the detector more distant from it. However because of quantum uncertainty there is no way to know in what direction this information transfer occurs. Superluminal transfer of information without superluminal signals is only possible in a theory that claims probabilities are irreducible.
Physicists often claim that there is no superluminal transfer of information predicted.
They claim that something is happening that does not fall within the domain of our classical mathematics. There is not a shred or experimental evidence that suggests it does not. There have been experimental tests but none of them are conclusive. The experimental verdict is still out on locality in nature. Bell's result has, to a degree, converted the metaphysical measurement problem to an experimental question.
